To all whomit concern:

Be it known t at I, DREW REYNOLDS, a citizen of the United States,residing at Marion, in the county of Williamson and State of Illinois,have invented certain new and useful Improvements. in Telescopic Handlesfor Combined Scrapers and Tampers, of which the following is aspecification, reference being had to the accompany in drawings. I i

This invention relates to the art of mming tools, and particularly to animproved extensible telescoping handle for miners scrapers and tampers,and an object of the invention is to rovide a handle of this characterwhich is made extensible so that a miners tool may be held at anydesired len h from the hand of the user.

other object of theinvention is to provide an extensible handle, whichis capable of attachment to various mining tools, especially tampers andscrapers, so that when the miner moves from one place to another it maybe accomplished with greater ease and less inconvenience, as it ispossible to collapse the handle to a very small compass hardly muchlonger than the tool, such as the tamper or the scraper, and may beeasily carried in a tool box, which. can be carried very easily.

A further object of the invention resides in the fact that an extensiblehandle for use in connection with a plurality of tools, is by farsuperior to carrying a plurality of tools, each having separate rigidhandles.

A still further object of the invention-is that a single extensiblehandle with a plurality of mining tools can be put on the market for arelatively low cost with a remuneration of a reasonable profit, and at aconsiderably less outlay than by manufacturing a plurality of toolshaving their own handles.

The invention still further aims to provide a very simple, eflicient andpractical extensible and telescoping handle com rising a plurality ofhandle sections, an including a novel form of holding connection ormeans between the handle sections, so that the handle will be rigid whenin use, and so that the sections may be easily collapsed, 'when thehandle is in storage or carried in a miners tool chest.

An additional object of the invention is to provide a holding connectionbetween the sections of such construction that the sections can be veryeasily manipulated for collapsing them, whenit is desired to place thehandle in the tool box. This folding connection is so constructed andincludes means, whereby it is unnecessary to hold the latch of theconnection the entire time the handle sections are beingtelescopicallycollapsed. It is only necessary to raise the latches one at a time, andimpart a slight turn to each section, then they may be easily andquickly collapsed by applying pressure upon both ends of the handle. Theextensible handle may be adjusted to difierent lengths as may be foundnecessary, by those using the handle.

While the design and construction at present illustrated and set forthis deemed preferable, it is obvious that as a result of a reduction ofthe invention to a more practical form for commercial purposes, theinvention may be susceptible to changes, and the right tothese changesis claimed, provided they are comprehended within the scope of what isclaimed.

The invention comprises further features and combination of parts, aswill be hereinafter set forth, shown in the drawings and claimed. V

In the drawings:

Figure 1 is a view in elevation of the improved extensible handleshowing the handle sections extended,

Fig. 2 is a view in elevation of the extensible handle showing thesections collapsed,

Fig. 3 is a sectional view on line 3-3 of Fig. 1,

Fig. 4 is a detail perspective view showing the joint between two of thesections: of a the handle, and

Fig. 5 is a sectional "iew on line 55 of Fi 4.

Feferring more especially to the drawing. 1 designates a tool shankwhich may terminate in any suitable mining tool, such as a scraper ortamper, as indicated at 2. The shank 1 merges into the handle, whichcomprises a plurality of handle sections 3, 4, 5 and 6. In fact, thetool shank 1 merges in any suitable manner into the smaller tubularhandle section 3. The handle section 6 at one end merges into a tam er7, which mag be constructed of any suitable metal, an is provided with acopper tip 8. Obviously, it will be noted the handlecarries PatentedJan. 18, 1921.

two diflerent kinds of tools, for instance, a scraper 'on one end, and atamper on the other. If desired, other sections similar to 3 and 6 maybe provided aml may have other forms of tools. other than scrapers andtampers.

The handle sections are provided with a plurality of transverselydisposed segmental or arcuate slots 9 at spaced intervals throughout thesections. These slots or notches at certain ends of their bottoms haveshouldersll), and from the shoulders the bottoms of the notches or slotsincline, so that a catch may slide upon the incline. and then fall intoengagement behind the shoulder.

The sections of the extensible handle are provided with longitudinallyextending grooves 11, which are disposed adjacent cermm of the ends ofthe transversely disposed slots or notches so that the inclined bottomsof the hatches or slots will merge into the longitudinal grooves.

Certain of the ends of the handle sections, excepting the handle section3, are provided with spring tongues 12, which form integral parts withthe handle sections. These integral spring tongues 12 are formed byslitting the tubular sectlons as indicated at 13, and the ends of thespring tongues tcrmlnate 1n lateral lugs 14, which engage thetransversely disposed arcuate or segment slots, that is to say, when thehandle sections are extended. In fact, the lateral lugs 14, when thehandle sections are adjusted to the length desired, engage behind theshoulders of said arcua-te or segment slots or notches so as to hold thesections in their extended positions. However, when it is desired tocollapse the sections, and to adjust the sections into a differentlength, then each of the spring tongues may be pulled from thetransverse slots or notches, sufficiently to pass over the shoulders,when a partial turn is imparted to the sections. The tubular handlesections may be further rotated, until the lugs 14 are in a position toenter the longitudinal grooves or slots, and then the handle sectionsmay be collapsed to other extended positions, or to a collapsedposition, for storing the handle away or for placing the handle in theminers tool box.

The invention having been set forth, What is claimed as new and usefulis:

1. In an extensible handle for tools, the combination with a pluralityof tubular handle sections telescopically united, of tools carried bythe remote ends of the end handle sections, said handle sections havingtransversely disposed arcuatc slots or notches provided with a retainingshoulder, the corresponding ends of certain of the handle sectionshaving spring tongues provided with lateral lugs engaging into saidslots or notches in engagement with and behind the shoulders, to holdthe handle sections extended and against rotation relatively to eachother, the handle sections hav ing longitudinally extending grooves,positioned adjacent certain of the ends of the arcuate slots or notches,which are provided with inclined bottoms merging into the longitudinalgrooves so that by lifting the tongue over the shoulders, the laterallugs may cam into engagement with the longitudinal grooves, for thepurpose of collapsing the handle sections.

2. In an extensible handle for tools, the combination with a pluralityof tubular handle sections, the end sections having their farther endsterminating in mining tools, slot and spring device connections betweenthe handle sections to hold them in extended positions, said handlesections having longitudinal grooves extending adjacent certain of theends of the slots of said connections, and slots of said connectionshaving inclined bottoms merging late the longitudinal grooves, tofacilitate the collapsing of the tubular handle sections, withoutholding the spring devices of said connections by hand, while thesections are being collapsed.

3. In an extensible handle for tools, a plurality of tubular handlesections telescopically united, certain of the sections having on theirexterior surfaces longitudinally extending grooves provided with lateralgrooves arcuate in form, each of said lateral arcuate grooves having aclosed end remote from where the grooves merge into the longitudinalgrooves, said closed end having a shoulder, corresponding ends of thesections being provided with parallel slits causing spring tongues to beformed between the slits, said tongues having lateral lugs adaptcd toengage the longitudinal grooves when collapsing or extendlng the handlesection, and when the sections are either in collapsed or extendedpositions, said lugs adapted to engage the lateral arcuate grooves byimparting a partial rotary movement to each section until the lugsengage said shoulders.

In testimony whereof I hereunto affix my signature.

DREW REYNOLDS.
